RAD21 and cardiovascular disorder: We constructed an mRNA–miRNA–lincRNA ceRNA interaction network centered on miR-22-3p and used the starBase v2.0 and miRWalk databases to predict eight related transcription factors associated with cardiovascular disease, namely, CTCF, JUN, JUND, NFATC1, NFE2L2, RAD21, RELA, and TAL1.
